Mod functions

mod.config_tab

Your mod can have an optional config page that is accessed through the Mods menu.

Setting Up Your Config

Create the structure of your config in a file named config.lua stored in your mod directory. SMODS will take this and assign it as the config for your mod, handling modifications and reloading internally. Your config.lua file should follow a structure like this:

return {
	["setting_1"] = true,
	["setting_2"] = {
		["option_1"] = 50,
		["option_2"] = 3,
		["option_3"] = false,
	}
}

You can access your config inside your mod by using this set up local config = SMODS.current_mod.config. Following this, using config.setting_1 would give you the value of setting_1 in your config.

Creating a Config Tab

To create a config tab, use this block of code.

SMODS.current_mod.config_tab = function()
	return {n = G.UIT.ROOT, config = {
		-- config values here, see 'Building a UI' page
	}, nodes = {
		-- work your UI wizardry here, see 'Building a UI' page
	}}
end

mod.extra_tabs

You may want to create additional pages besides your config tab.

Creating Additional Tabs

To create additional tabs, use this block of code.

SMODS.current_mod.extra_tabs = function()
	return {
		{
			label = 'My Label',
			tab_definition_function = function()
				-- works in the same way as mod.config_tab
				return {n = G.UIT.ROOT, config = {
					-- config values here, see 'Building a UI' page
				}, nodes = {
					-- work your UI wizardry here, see 'Building a UI' page
				}}
			end,
		},
		-- insert more tables with the same structure here
	}
end

mod.custom_collection_tabs

This sets up additional collection pages to be accessed through the 'Other' button.

SMODS.current_mod.custom_collection_tabs = function()
	return {
		{
			button = UIBox_button({
				-- calls `G.FUNCS.your_collection_something` when pressed, define accordingly
				button = 'your_collection_something', 
				id = 'your_collection_something',
				-- Displayed label on the button (using non-localized strings also works)
				label = {localize('b_your_label')},
				-- optional; should have numeric 'tally' and 'of' values (for discovery counts)
				count = G.DISCOVER_TALLIES['something'], 
				-- optional; minimum width of your button
				minw = 5,
			})
		},
		-- add more buttons here
	}
end
G.FUNCS.your_collection_something()
	G.SETTINGS.paused = true
  	G.FUNCS.overlay_menu{
    	definition = create_UIBox_your_collection_something(), -- this is the actual UI definition function
  	}
end
-- define `create_UIBox_your_collection_something()` to create the collection, see 'Building a UI'

Advanced Mod descriptions

Default mod descriptions defined within your mod's metadata supports basic text wrapping, but no further formatting like changing the colour and scale of text or inserting variables, as well as localization. By using Localization files, you can create a description for your mods with support for all the formatting of other descriptions. Your description should be placed in G.localization.descriptions.Mod[mod_id].

mod.description_loc_vars

To change your description dynamically through variables and alternate keys or specify a default text colour and scale, you can define this function on your mod object. This function behaves like loc_vars on other objects.

SMODS.current_mod.description_loc_vars = function(self)
	return {
		vars = { 'some var', colours = {HEX('123ABC') }}, -- text variables (e.g. #1#) and colour variables (e.g. {V:1})
		key = 'alternate_key', -- Get description from G.localization.descriptions.Mod[key] instead
		scale = 1.1, -- Change text scale, default 1
		text_colour = HEX('1A2B3C'), -- Default text colour if no colour control is active
		background_colour = HEX('9876547F')
	}
end

mod.custom_ui

This function can be used to manipulate your mod's description tab arbitarily. It receives a table of nodes as an argument, you can modify this table to insert additional elements or modify existing ones. See also: Building a UI.

mod.debug_info

This is a property that can be set by mods to show debug information on the crash screen.

• Setting this to a string will display that string under your mod in the crash screen.
• Setting this to a table of strings will display a list with each key and its value under your mod in the crash screen.

In-game functionality

You may want to have some functionality happen with your mod installed independently of some other object being present. For cases like this, defining these mod-scope functions is a good alternative to destructively modifying the underlying vanilla function and helps preserve compatibility with other mods.

mod.reset_game_globals(run_start)

Set up global game values that reset each round, similar to vanilla jokers like Castle, The Idol, Ancient Joker, and Mail-In Rebate. run_start indicates if the function is being called at the start of the run.
